I know there's already a thread for this, but I can't get an answer. My SX-990 reads 130+mv each for dc offset. How do you adjust it, or is it one you can't adjust?
I've got a service manual coming. If my altzheimers does not override my intentions, and the answer has not been forthcoming before the manual arrives, I'll post your answer. I have a real nice one that I'm refurbing for sale as we speak...
